I have used GE silicone "kitchen and bath" for years, but the caulk in the bathtub always develops black mildew within 1-2 years and needs to be removed and replaced.  Is there a better product that will not develop mildew so quickly?  thanks.

I've always used DAP's bathroom caulk.  Seems to hold up pretty well.

One hint is to buy some Clean Shower spray and spray down the problem areas after usiing the shower or whatever.  This helps the soap scum to drain off, so less of a foundation for mildew.

Never use silicone caulk in your bathroom. The caulk around your tub is a maintenance item meaning it needs t be redone every 4 or 5 years. Silicone is almost impossible to remove and new caulk doesn't stick to it well. Use a razor scraper and a big box of elbow grease and remove it all, every smigen. Use a blue scotch Brite pad to finish cleaning. Then use a good Kitchen and Bath latex caulk. If and when it mildews cut it out and do it again.
